HANS KREIDEL, OF WIESBADEN, GERMANY LIQUID ATOMIZER Application filed May 28, 1930, Serial No. 456,583, and in Germany September 29, 1929.

The present invention relates to a liquid atomizer for perfume and the like, which at the same time forms for support for the vessel, bottle or the like, containing the liquid to be dispersed, and which can be actuated by one hand. It permits of clamping liquid containers such as flasks of the most diverse type and height so that it is possible, without pouring out and without loss of liquid to lo atomize the liquid directly from the vessel in which it is sold, for example from perfumery bottles which are mostly constructed of very tasteful appearance.

i The new liquid atomizer consists of the la actual atomizing device and a supporting plate for the liquid vessel, for example the perfume bottle, arranged parallel thereto. Both these members are connected together by a shaft located on one side which is exten- EQ sible and which at the same time forms the handle. The shaft itself consists of two parts resiliently connected together. These parts are preferably formed of two tubular members telescopically fitted one upon the other 2G and rotatable about their axis. The spring to the action of which they are exposed and which draws them together is located within the innermost tubular member. Y

Spaced laterally from the connecting shaft, simultaneously forming the handle of the atomizer, there is provided on a laterally extending arm the stand pipe for the liquid to be atomized.

For closing the opening of the vessel or bottle the stand pipe may be provided with a sliding and spring actuated closure member (packing disc, plug or the like) or a similar closure member may also be immovably secured to the horizontally extending arm at the point of closure of the stand pipe. The firstmentioned movable arrangement of the closure member is selected when the liquid containers, for example bottles, are of a height which is less than the distance between the closure plate and the horizontal arm carrying the atomizing nozzle. The other construction with the stationary closing member may be used when the liquid containers, for example bottles, are of considerable height.

In any case the stand pipe is preferably provided with an extensible extension member. ln this form of construction the spring located in the shaft which simultaneously serves as the handle is also adapted to press the opening of the container against the closing closure member. Y

In the accompanying drawing are illustrated two examples of construction of the invention and their method of use.

Figures l and 2 show one form of con- 60 struction for use with a low liquid container, Figure 1 being an elevation and Figure 2 a section with the supporting plate for the liquid container swung laterally. K

Figure ,3 shows the method of use or the 05 atomizer in use, and

Figure 4 shows a section to another form of construction for liquid containers of considerable height.

fn Figures l to 3, a indicates the supporting plate for the liquid container, for example a bottle b, containing the perfume or the like to be atomized. At one end of the supporting plate there is provided a bearing pan 0 formed by an annular raised edge into 75 which is rotatably fitted the hollow shaft CZ, simultaneously forming the handle, for the actual atomizing device. The pivot e passes through the bottom d of the shaft and is ysecured in the supporting plate a in any suit- S0 able manner. Between its enlarged head e and the bottom ci of the shaft there is provided a spring f wound around the pivot e. The shaft d is movable longitudinally on the pivot e for a predetermined distance and is always urged by the spring f towards the supporting plate. A slot c open at the top and located in the projecting rim of the bearing pan and a pin cl2 projecting outwardly from the shaft 0l form a pin and slot joint 90 and secure the shaft in the correct position `when the liquid container b has been fitted in position. rlhe shaft 0l is provided at the top with a shell g for seating a rubber ball h, adapted to be used as a blower, and is also provided with a horizontal tubular arm rthrough which the air from the blower (rubber ball) reaches the blower nozzle 7c. At an angle to the nozzle is located the suction nozzle l of the stand pipe m leadinginto the liq- 300 uid container (the bottle) and together with this is secured by a cap nut n in the vertical limb of a T-piece 0 screwed to the free end of the tubular arm z'. Opposite the blower' nozzle 7c there is screwed into the horizontal portion of the T-piece o the common outlet nozzle p.

On the stand pipe m slides an apertured closure plug r which is under the action of a spring s bearing at one end against the cap nut n and constantly tending to press the plug downwardly, that is to say against the neck opening of the liquid container or the bottle b and thus to close this and also the passage of the stand pipe m in a Huid-tight manner. The spring f of the shaft cl must not be weaker, but on the contrary should be stronger than the plug pressing spring s for the container closure. y

The method and manner of using the liquid atomizer described will be readily seen from Figure 3. c

After the bottle l) with the liquid 'to be atoinized has Abeen clamped between the supporting plate t an the actual 4atomizing device or the spring actuated closure plug a' mounted on the stand pipe m and forming a part of the atomizing device, the shaft i is O'ripped by the four lingers of one hand. lVhen thus held the atomizer may be operated by pressing the thumb on 'the blower 7L (the rubber ball) to produce the necessary compressed air for drawing the liquid from the bottle and atoinizing it. T he finely atornized liquid passes out of the nozzle p in the form of a mist. 1

l The actual liquid atomi'zing AVdevice does -not form the subject of the ,present Vinvention and may, therefore, be constructedi'n any suitable known manner. The essential 'feature of the invention resides in the clamping in position of liquid containers (bottles) of 'suitable shape and height. e

lhis is effected in the manner 'that the liquid container (the bottle) after previously moving the supporting plate laterally (Figure 2) is fitted 'from the bottom on the stand pipe m thus forcing back the spring actuated closure plug r. At the same time the shaft d is somewhat extended against the action of its stronger spring and the supporting plate a is swung underneath the liquid container (the bottle). l about the pivot e takes place until'the pin (Z2 of the shaft CZ can engage with vthe slot c 'of the projecting rim of the bearing pan c and 'thus secures the relative position of the pivoted parts of the shaft or handle and the Vatomizing device and supporting vplate carried thereby. When unclamping or removing the liquid container (the bottle) '-the shaft Z is again extended against the action of its spring until the pin Z2 passes out of the 'slot c', -thenthe supporting plate a Vis swung -ou'twardly and the liquid container (the bottle) In this connection rotation' is withdrawn downwardly from the stand pipe m.

In Figure 4 A indicates the supporting plate for the liquid container, B (the bottle), C, C the extensible shaft with the shell D for seating a rubber ball E, serving as a blower, and a tubular 'arni F 'for applying the suction to 'and vatomizing the liquid by the compressed air. produced. The stationary part CV of the shaft on the supporting plate A also forms in this form of construction a tubular member onf which the other part C, carrying the atomizing device, is telescopical- The shaft portion C is provided with a longitudinal slot G which 'at the top terminates in a transverse slot G and the shaft 'porti-on 'is provided with a guide pin H 'engaging with the `sai-d slot G. The length of this slot limits the extent by which the two shaft parts C, C can be extended; When the lguide pin H has reached the upper end of the slot G, when extending the shaft parts, then on the rotation 'thereof it engages with the transverse slot G and holds fthe parts in the extended position. The spirally wound tension `spring located within the shaft part C is lsecured at its lower end to a transverse pin of the shaft part C and at its upper end is suspended from a hook'of the shaft part '(1.

The actu-al atomizing `dev-ice differs somewhat from that illustrated in Figures l to 3. The stand pipe J -is provided with yan extensible extension and 'an angular branch K `which is freely open directly in 'front of the outlet nozzle L so tha-t the stream of air passing through F can pass around the branch .K and through "the passage for-ined between the free end of the branch andthe wall of the outlet nozzle -L and is-also capable of passing through the nozzle itself 'thus drawing the liquid outof the 'bo't-tle The ystand pipe l and its branch K fare :secured Yin :a separate member M fitted intothe tubular .arm 1F, the member M being constructed in a particular ymanner for the reception of a vnozzle cleaning needle N "which -can be unserewed. `@pposite this member M there is :secured in the tubular afrm F a" protecting pipe O, for the stand pipe -J iprovided with the extensible ext'ei'isiom the pipe O 'being provided with an vannular row of Lair inlet 'openings This protecting pifpe i@ is provided with a cap bearing against thetubular iarm F 'and iit'ted with a packing plate P of rubber or the like "which closes the Aopening of the liquid containe'ror bottle pressed against it from underneath. The device iis used inthe same manner as the other 4construction shown in Figures -lfan'd 2 and lin the manner illustrated in Figure f3.

For Aremoving the bottle the shaft CJC', simult'arfeoursly forming the handle, -is lextended against fthejaction of the spring l -until 'the guide'pin-H ofthe'ishaftpartC =is`on a level with a transverse slot G of the other shaft part C and permits axial turning of the two parts. Simultaneously with the turning and lateral swinging of the supporting plate A the bottle B can be withdrawn downwardly from the stand pipe J and its protecting pipe O.

When another bottle is to be placed in position this is fitted on the extensible stand pipe and compressing this upwardly to such an extent that its openingvbears against the packing plate P. The supporting plate A is then swung back into its position so that it engages unde-r the bottle. As now the spring l is again capable of exerting its full force the bottle is clamped between the supporting plate and the tubular arm, and its opening is pressed firmly against the packing plate P.
